The MaxAI Alternative for Your Own AI Keys
MaxAI is an all-in-one sidebar with AI usage in a monthly plan. Prompt Anything Pro prompts any text you select with 30+ models on your own keys, or local AI with no key. $6.99/month or $49.99 lifetime.
TL;DR
MaxAI is an AI assistant for Chrome, Edge, and the web that combines chat with pages, PDFs, and videos, web search, image creation, and quick actions on selected text, with AI usage included in its plans. Prompt Anything Pro is narrower and deeper: select text on any webpage, get template suggestions based on what you selected, and send it to one of 30+ models from OpenAI, Anthropic, Google, xAI, and Groq using your own API keys, or to a local model or Chrome's built-in AI with no key. It costs $6.99/month or $49.99 lifetime, and you pay your AI provider directly for what you use.
Where MaxAI May Not Fit
A subscription with no end date
MaxAI's paid plans are monthly or yearly subscriptions, and no lifetime plan is listed, so the cost continues for as long as you use it.
Cloud models only
MaxAI lists cloud models from OpenAI, Anthropic, Google, and Meta, but no local or on-device option, so the text you select always goes to a cloud model.
Usage limits by plan
MaxAI caps usage per plan, and its stronger models are limited on lower tiers unless you add your own API keys.
A big sidebar for quick tasks
MaxAI packs chat, search, PDFs, and image tools into one sidebar. If you mostly run the same prompts on selected text, that's more interface than you need.
